Does the Sepam series 40 keeps the internal time in case of loss of the auxiliary supply?

For Sepam series 40, units released before mid 2010 the internal clock is being kept by a capacitor up to 24 hours after a power outage. An additional capacitor added on units released after mid 2010, the disturbance recordings are guaranteed to be kept within 48 hours after the power outage.

As additional information; the Sepam parameters and protection settings are being saved in a non-volatile memory. Other data are also being saved in the non-volatile memory, and you can see them in the files that I have attached.
